Background

Gastric tubes, also known as nasogastric tubes, help patients who cannot swallow to deliver the necessary moisture and food under special circumstances. The stomach tube is generally made of polyurethane or silica gel materials, and the polyurethane and silica gel stomach tubes should be changed once a month according to the materials. The sizes of the stomach tubes are different, and the stomach tubes are oral stomach tubes and nasal stomach tubes. Wherein, the length of the orogastric tube is about 45Cm, and the orogastric tube can be inserted into the mouth by 35-40 Cm. The nasal feeding tube is about 105Cm long, is required to be inserted into a nostril to be about 55Cm, passes through the pharynx and reaches the stomach through the esophagus, is easy to separate from the nasogastric tube, is firmly adhered, prevents repeated intubation and aspiration, and consists of a pipeline, a stomach tube feeding port connector, a stomach tube clamp and a cross-shaped knot blocking cap. Nasogastric tubes are an essential procedure for patients who require gastrointestinal decompression, such as gastrointestinal perforation, intestinal obstruction, and acute abdomen, patients who cannot take food orally due to coma and require enteral nutrition, patients who require gastric lavage for poisoning, and the like.

Most of the current nasogastric tubes have the following problems: firstly, when imbedding the stomach tube, owing to use stomach tube material and stomach tube pointed end, often can cause the damage of stomach and esophagus mucosa, nose mucosa. Even direct gastric tube puncture of the stomach wall has been reported, and this damage is certainly quite severe for patients; secondly, the nasogastric tube is arranged in the esophagus, the original digestive tract physiological environment of a patient is changed, the sphincter at the tail end of the esophagus is not closed tightly, the airway is not blocked, and pressure stimulation such as severe cough easily causes complications such as esophagus reflux and the like.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-2, the present invention provides a technical solution: a nasogastric tube capable of reducing gastric injury comprises an esophagus 1 and an airway 2, and is characterized in that: the utility model discloses a esophagus, including esophagus 1, gasbag 6, fixed band, fixed nose plug 7, the bottom and 6 fixed connection of gasbag 6, esophagus 1's bottom is provided with balancing weight 4, esophagus 1's the bottom outside and the inboard outer wall fixed connection of gasbag 6, liquid food hole 5 has been seted up to esophagus 1's below bilateral symmetry, the top of esophagus 1 and the bottom fixed connection who annotates food joint 8, it passes through fixed band 11 and airtight lid 3 fixed connection to annotate food joint 8, esophagus 1's middle part is equipped with fixed nasal obstruction 7, the bottom and the 6 fixed connection of gasbag of air duct 2, the top of air duct 2 and the bottom fixed connection of airtight pneumatic valve 9, the upper end of air duct 2 is provided with pressure detector 10,

air duct

2 and 1 upper.

Wherein, the balancing weight 4 is spherical, and the number of the balancing weight 4 is two, so that the bottom end of the nasogastric tube is added with the balance weight; the bottom of the esophagus 1 is hemispherical, the air bag 6 is annular in plan view, the air bag 6 is elliptical in front view, the air bag 6 is positioned at the bottommost part of the esophagus 1 and just surrounds the bottom end of the esophagus 1, so that the tail end of the device is smoother, and the damage to the stomach wall by the tip is reduced; the liquid food holes 5 are round, the number of the liquid food holes 5 is four, and the liquid food holes 5 are positioned at the lowest end of the inner cavity of the esophagus 1 and are symmetrically distributed in a crossed manner, so that the esophagus 1 can be fed more smoothly, and blockage is avoided; the air bag 6, the closed air valve 9, the pressure detector 10 and the inner cavity of the air duct 2 are communicated.

The working principle is as follows: when the nasogastric tube capable of reducing gastric injury is used, firstly, pressurized gas is injected into an air bag 6 through an air guide tube 2 by taking a needle cylinder through a closed air valve 9, when the size of the air bag 6 reaches a preset size, the nasogastric tube is guided into a stomach through a nasal cavity, attention should be paid to a pressure detector 10 at the moment, the air bag 6 is placed to be broken, and the like, the gas in the air bag 6 is extracted through the air guide tube 2 by using the needle tube through the closed air valve 9, and at the moment, the esophagus stably falls into a gastric cavity under the influence of a balancing weight 4; when food is required to be injected, the closed cover 3 is firstly opened, food is injected into the food injection joint 8 by using the needle cylinder, the food flows out through the liquid food hole 5 after passing through the esophagus 1, and the closed cover 3 is closed in time when the food injection is completed.
